The following package is going to be installed:

- zsync-0.6.2-11.1.mga9.i586

195KB of additional disk space will be used.


----

I created zsync file on an http server

Then ran

$ zsync http://mageia-highland.us/mageia/iso/9/Mageia-9-Live-Xfce-i586/Mageia-9-Live-Xfce-i586.iso.zsync


it worked.

Ran it again, it sync'd and made a backup as designed.

Installed 64bit version

Went to a directory with an existing matching iso and ran zsync

It compared and closed

I think this is good to go.
